Coupling set for connecting ground plate for arrest of lightning

ABSTRACT

A coupling set for connecting a ground plate for arrest of lightning is provided, in which the ground plate is embedded underground below an electric pole in order to effectively arrest lightning. Accordingly, lightning can be effectively grounded. The connection members are connected with each other top and bottom and left and right. The lowest connection member is supported below an electric pole. Thus, when the electric pole is buried, a coupling set having connection members for connecting a ground plate is not be pushed up. Also, it is very easy to connect a lightning arrest copper wire with a ground terminal.

TECHNICAL FIELD

The present invention relates to a coupling set for connection of alightning arrest ground plate, and more particularly, to a coupling setfor connecting a ground plate for arrest of lightning, in which theground plate is embedded underground below an electric pole in order toeffectively arrest lightning.

BACKGROUND ART

The Inventor has improved his previous registered Korean Utility Modelentitled “a coupling set for connection of a lightning arrest groundplate” disclosed in Korean Utility Model Publication No. 20-2002-282258on 19 Jul. 2002. In the Korean Utility Model Publication No.20-2002-282258, a coupling set for connection of a lightning arrestground plate is embedded and buried below a burial place of an electricpole. Here, the coupling set for connection of the ground plate is notfixed at a fixed position but pushed and raised along the electric pole.Also, separate clips are needed to combine lightning arrest copper wireswith ground terminals.

DISCLOSURE OF THE INVENTION

To solve the above problems, it is an object of the present invention toprovide a coupling set for connecting a ground plate for arrest oflightning in which when the electric pole is buried, a coupling sethaving connection members for connecting a ground plate is not be pushedup, and it is also very easy to connect a lightning arrest copper wirewith a ground terminal.

To accomplish the above object of the present invention, there isprovided a coupling set for connecting a ground plate for arrest oflightning in which a stopper is needed in order that the connectioncoupling set of the ground plate may not secede from the bottom surfaceof an electric pole.

Also, when the connection coupling sets of the ground plate areconnected with one another in the lengthy direction, and the lowestground plate connection coupling set is fixed, the other ground plateconnection coupling sets are fixed in series. Further, since groundterminals are also configured into a clip or tightener shape of a simpleshape, ground copper wires can be easily combined with the groundterminals without having a fixing clip on a working site.

BEST MODE FOR CARRYING OUT THE INVENTION

A coupling set for coupling a ground plate for arrest of lightningaccording to a preferred embodiment of the present invention will bedescribed with reference to the accompanying drawings.

Referring to FIGS. 1 and 4, a coupling set for connecting a ground platefor arrest of lightning according to the present invention has astructure where a first connection member 1 and a second connectionmember 2 which are connected horizontally with each other are positionedat the upper portion of the whole coupling set, and a third connectionmember 3 and a fourth connection member 4 which are connectedhorizontally with each other are positioned at the lower portionthereof. Then, the first connection member 1 and the second connectionmember 2 are connected vertically with the third connection member 3 andthe fourth connection member 4, respectively. As shown in FIG. 4, thefirst connection member 1 and the second connection member 2 areconnected with each other by means of tightening belts 12 in a burialportion of an electric pole 18, and likewise the third connection member3 and the fourth connection member 4 are connected with each other bymeans of tightening belts 12 in the burial portion of the electric pole18. A ground copper plate 13 of FIG. 2 is mounted on mount seats 9 ofspacers 8 formed on the respective connection members 1 to 4, so thatthe ground copper plate 13 is connected on the connection members byleft-hand and right-hand coupling portions shown.

Referring to FIGS. 3A and 3B in the present invention, an upperconnection piece 5 having a key protrusion 5-1 is formed on the upperportion of first and second connection members 1 and 2, respectively,and an upper connection groove 6 having a key groove 6-1 is formed onthe respective lower portions thereof. An upper connection piece 5having a key protrusion 5-1 is formed on the upper portion of third andfourth connection members 3 and 4, respectively, and at least one lowersupporter 7 is formed in the respective lower portions thereof. A groundcopper plate 13 combined with a ground terminal 14 is mounted on mountseats 9 of the connection members 1 to 4, so that the ground copperplate 13 is horizontally mounted.

The ground terminal 14 includes a lower fixing portion 15, a middle bentportion 16, and an upper combiner 17 whose ends are open. In the presentinvention, the connection members 1 and 2 are horizontally connectedwith each other, and the connection members 3 and 4 are horizontallyconnected with each other, and then the connection member 1 and theconnection member 2 are connected vertically with the connection member3 and the connection member 4, respectively, in which the upperconnection piece 5 is combined with the upper connection groove 6. Then,the connection members 1 to 4 which have been connected to each otherare combined with the lower portion of an electric pole 18 by means oftightening belts 12, and then the ground copper plate 13 is horizontallywound around and combined with the connection members. Thereafter,lightening arrest copper wires are connected with the ground terminal14, to thereby complete preparation of burial of the coupling device forconnection of a ground plate to arrest lightening, together with theelectric pole 18. Here, lower supporters 7 formed in the lower portionsof the respective third and fourth connection members 3 and 4 and bentinwards therefrom are supported on the bottom surface of the electricpole 18 and thus prevent the connection members from being pushed up andraised. The first and second connection members 1 and 2 can be combinedin a multiple layer as many as the number desired by a designer. Here,couplers for connecting the first and second connection members 1 and 2are upper connection pieces 5 and upper connection grooves 6. The upperconnection pieces 5 and upper connection grooves 6 are connected in afemale-to-male fashion, and vertically. Meanwhile, the ground terminal14 is a simple linear-shaped terminal, but has an upper combiner 17whose ends are open such as a clip or joint terminal. Accordingly,lightening arrest copper wires 19 are fitted into the combiner 17 andthen the combiner 17 is tightened by a tightening tool to thereby easilyconnect the lightening arrest copper wires with the ground plate.

INDUSTRIAL APPLICABILITY

As described above, the present invention provides a coupling set forconnecting a ground plate for arrest of lightning in which respectiveconnection members are connected with one another, in all directionssuch as left, right, up and down.
